DENVER, COLORADO, A CORPORATION orcononAno CELL CONSTRUCTION Fon-FIoTATIonMAcHINi-is Application filed September 14, 193 1.' Serial No. 562,748.

This invention relates to improvements in flotation machines and relates more particu-' larly to the construction of all steel machines.

It is the object of this invention to produce a construction of the cell of a flotation machine that shall adapt it to be made from steel and which shall be so designed that it can be readily taken apart for shipment and' assembled at the place Where the machine is to be used, thereby effecting a large saving in freight.

Flotation machines of the type to which this invention relates are usually arranged in groups of two or more cells and one of the objects of this invention is therefore to produce a cell construction that readily lends itself to being assembled in groups of any desired number of units. 0

This invention, briefly described, consists in a cell construction having straight transverse metal partitions of a special design or construction connected by sheet metal sides and bottom formed integral with each other and bent into U-shape and the ends of whlch are provided with flanges that are adapted to fit against the partitions and to be secured to the latter by bolts. i

The partitions which form the distinguishing feature of this invention are each prov1ded with a chamber or compartment extending downwardly from the top and divided by removable plates in a manner to be hereinafter described.

Having thus briefly described the general construction the same will now be described in detail, and for this purpose reference will be had to the accompanying drawing in which the preferred embodiment has been illustrated and in which:

Fig. 1 shows a plan view of two cells constructed in accordance with this invention;

Fig. 2 is a transverse section taken on line 2-2, Fig. 1; and

Fig. 3 is a section taken on line 33, Fig. 2.

In the drawing the invention has been illustrated in connection with two adjacent cells A and B. The end walls of the cells are formed by partitions 1 and a similar partition is located between the two cells 50 and forms a common end wall for both.

The'central partition in orderto distinguish it from the others, has been designated by reference numeral :2. .These end walls and partitions are formed of flat metal'sections which are preferably cast either fromicast iron 'or steel and: are provided centrally with a rectangular compartment 3. The partition has a portion of its area formed by two spaced walls separatedso as to form a compartment, the lower ends of the -walls are connected to the partition to form a bot- .tom for the compartment as shown most clearly in Fig. '1. The innersurfaces of the end walls havevertical grooyes' for the reception of removable-plates which divide the compartment into two portions. Each of the side walls has an opening near the lower end; When pulp flowsfrom one cell to the next adjacent one, it passes through one of the openings into the part of the compartment on that. side of the center plates and flows over the top of these plates into the other part of the compartment and out through the opening into thenext cell. The partitions constructed as described,

make it possible to build 'a cell assembly of any number of cells very easily. The

bottom, the'front and rear sides of each :cell

are formed from a single sheet of steel which has been indicated by reference 'nu- Ineral 4. This sheet is bent into U-shape ing flange lies in a plane slightly beyond the ends of the sheetand is perforated for the reception of bolts 6. The end walls and the partitions are also perforated to correspond with the perforations in the flanges .and therefore the cells can be quickly built up by merely bolting the end walls to the angle irons in the manner shown in Figs. 1 and in Fig. 3. At the ends of the cells the members 1 form the extreme end and therefore only one angle iron fits against these end members, whereas, the center partitions have an angle iron on each side as Shown in Fig. 3.

From the above description it will be evident that the cell construction shown and described'can be very readily taken apart for shipment and assembled on the job and in this way a great saving is effected in the expense of transportation.

tion shown is also extremely simple and The construccheap compared to other constructions and besides this it forms a very substantial cell thathas a long life and will withstand abuse to a much greater extent than cells made partly of wood.

Having described the invention what is claimed as new is:

1. In a flotation machine comprising a number of cells separated by partitions that form a common wall for two cells, each partition comprising a substantially rectangular; plate having a portion of its area formed from two spaced walls whose sides and lower ends are joined to the plate whereby a compartment is formed that is open at the top, the inside surfaces of the end walls of the compartment having grooves for the reception of removable separator plates that divide the compartment into two parts, the side walls having openings'near their lower ends whereby liquid may flow from one cell to the next by flowing through one of the openings into the compartment and then over the separator plates and out through the opening in the other compartment wall.

2. A common partition for two adjacent flotation cells comprising a substantially rectangular plate having a portion of its area formed from two walls spaced apart and connected at their sides and lower ends with the plate so as to form a compartment open at the top, the inner surfaces of the end walls having groovesfor the reception of removable separator plates which divide the compartment longitudinally into two parts, each side wall having an opening near its bottom.

- 3. A common partition for two adjacent flotation cells comprising a substantially rectangular plate having a portion of its area formed from two walls spaced apart and connected at their sides and lower ends with the plate so as to form a compartment open at the top, the inner surfaces of the end walls having means for receiving and guiding a movable separator plate which divides the compartment longitudinally into two parts, each side wall having an opening near its bottom.

' In testimony whereof I affix my signature.
